Counterstrike 1.6 Online

I’m trying to play online with my mate, I made a hamachi network and got him to join, then I made a server on cs 1.6 and in console wrote sv_lan 0 to play online, and when he joins this happens. We are not playing on LAN.

What can I do? Don’t suggest me to buy it, as I already have source.
Answer #1
Anyone?
Answer #2
I’d suggest you host a dedicated server with a password on it. This way only your friend will be able to join your game.
I use Hamachi too for playing online games like Fifa.
Though when using a dedicated server, you won’t need hamachi.
Answer #3
just set on server sv_lan 0
